SNOW-PLOW.

SPECIFICATION forming part of Letters Patent N o. 734,026, dated July 21, 1903. Application tiled October 17, 1900A.' Renewed December 16, 1902 Serial No, 135,461. (No model.)

.To all whom it may concern,.-

Be it known that I, WARREN F. WHEELER, a citizen of the United States, and a resident of Stoneham, in the county of Middlesex and State of Massachusetts, have invented an Improvement in vSno'w-Plows, of which the following is a specification.

My invention relates to snow-plows for clearing s now from sidewalks and highways; and it consists in the improvements hereinafter described and claimed, and illustrated in the accompanying drawings, in which- Figure l is a-plan of aplow embodying my improvements. Fig. 2 is a side elevation of the same. Fig. 3 is a sectional elevation, the section being taken as on the dotted angular line X X, Fig. l. Figs. 4 and 5 are detached details which will be explained. Fig. 6 is a detail in perspective of the locking-plates.

Many of the details of construction in the plow shown in the drawings are not new, but are substantially the same as the like devices for similar purposes shown and described in Letters Patent No. {A8/749, issuedv to me April 24, 1894, but not claimed therein as in and of themselves novel, including the mechanism for swinging the wing of the scraper outward and the arrangement of levers for raising the plow. In my said former patent I employed two sleds pivotedtogether at their rear ends to serve as the base of the plow, upon one of which was'supported the plow and upon the other, the under and inner one, was arranged theplatform which supported the means for raising the plow, and the plow itself, when so raised, and the means for moving the wing hingedrto the scraper. The construction ofthe scraping side of the plow with its hinged wing and the means and manner of moving the wing are substantially the same as in my former plow, described in said patent, and in other plows used by me before that invention.

The chief feature of novelty in my present invention relates to that part of the construction by which I raise the scraper of the plow, together with its wing, independently of the opposite side of the plow to clear it from obstacles on the street-surfacewhile moving the plow from place to place, or whenever it may be desired to so raise it, and by which I am enabled to dispense with one of the sleds which I formerly employed for that purpose.

The plow as l now construct it consists of a sled A, comprising a long runner B-and a short runner B', with open tioor-planking C C, forming a platform extending across from the top of one'runner to the top ofthe other and unitingthetwo. Amoldboardorscraper D, having hinged thereto a wing D', forms an oblique side of the plow and extends from the short runner on the right side diagonally across to the long runner on theleft side and is so attached to said left'side as to have an independent vertical movement thereon, as will be described.

The left side E of the plow is firmly attached to runner1 B, formingtherewithaplain Vertical side, while the opposite scraper D is concave on its out-er face and is closely connected with side E in such manner as to be .supported with said side upon a common shoe E, secured to runner B at one end and upturned and secured at its opposite end to the projecting beam G, to which the drawbar H is bolted.

Upon the platform at I the mechanism for moving the wing D' is secu red, consisting of the jointed bar J, connected with the wing, a chain or cord K, attached at one end to bar 'J and at its opposite end to a vertical rod L,

arranged to be turned in proper bearings by a crank L', a ratchet M, secured to rod L, and

a pawl or detent N, secured to the platform and arranged to engage the teeth of the ratchet to prevent reaction when the chain is wound around rod L in the operation of thus moving the barJ and wing D in the wellknown manner. Bar J works-under a limiting-guard P, while the chain draws over the same, as shown. l employ the two levers R and S, one extending lengthwise of the plow near side E, while the other extends crosswise of the plow from the opposite side and across thepath of the long leverR to raise the scraper D and its wing D only. In my said former patent I used a similarv arrangement of levers to raisethe forwardv part of the entire plow, which was at suchtime supported upon the inner and under auxiliary sled pivoted thereto, as before stated. In

lOO

this case I discard the auxiliary sled and raise but one side of the plow, the scraper D and wings D' supporting them on the platform .of the plow through levers R and S and their attachments. In this construction, by which I do away with one sled and adapt the plow to be raised upon the scraping side only, lies the chief novelty of my present invention. I accomplish this purpose as follows:

Scraper D is secured on side E to a beam D2 and at its rear end on the opposite side of the plow to a beam D3. These upright beams or posts rise and fall with scraper D when it is raised and lowered. The beam D2 is secured to scraper D by being bolted to the curved rib E' on the inner face of the scraper and is connected with side E by means of eyebolts E2, screwed into a post attached to the inner face of side E, and eyebolts E3, screwed into beam D2, the eyes of all the bolts being arranged in vertical alinement and connected by a rod E4, passed down through the same and properly held therein, as clearly shown in Fig. 4t, which is a detail of said parts so connected, and as seen from a direction the reverse of the view in Fig. 2. The frontend of scraper D is thus held closely to side E near shoe F, while it has freedom for vertical movement to the extent required on the connecting-rod. The rear end of the scraper and its wing are similarly connected with a crossframe composed of upright side posts and a cross-beam T, extending from one side of the plow to the other. Eyebolts D4 are screwed into the upright standard of frame T adjacent to wing D', as shown in broken sections in Fig. 5, and corresponding eyebolts D5 and D6 are screwed into post D3, and all the eyes are arranged in vertical alinement and connected by rod D", passed down through the same and properly held therein. Post D3 has the required freedom of vertical movement on said rod when it is moved up and down with scraper D, to which it is firmly attached, which movement is produced simultaneously with the movement of the forward end of the scraper by the action of levers R and S, as will be explained.

The hingesYY on wing D', as clearly shown in Fig. 5, are connected with eyebolts Y and Y2, screwed into post D3, and through the eyes of which and the eyes of the hinges the rod Y2 is passed and secured therein, forming the pivot of the jointed connection of the scraper and its wing.

On rod Y3 a sleeve Y4 is placed, the upper end of which bears against the under side of the upper hinge, while the lower end rests on the short arm of lever S, which is arranged to lift the same, with post D3 and that part of the scraper that is attached thereto, at the same time that the forward end of the scraper is raised by lever R.

Lever R has vits fulcrum upon the platform at R2, and the iron point of its short arm rests under and against sleeve E5 on rod E4, as shown in Fig. 4. Lever S has its fulcrnm on the platform' near the hinge of the wing, and

its short arm is arranged to bear upward against the lower end of sleeve Y4 on rod Y3 to raise the same when the long arm of the lever is depressed. This lever, as before stated, extends across the platform of the plow and crosses the path of the longer lever R, which extends at right angles to lever S, and when lever R is depressed it carries down lever S, and thus they act jointly and simultaneously on the scraper and raise the same its entire length independently of side E, and when the scraper is thus raised to clear it from obstacles on the surface of the road, while the plow is moved from place to place or for any desired purpose, it is locked in such elevated position and supported by the levers by means of plate R', arranged on lever R to engage with notches T' on an adjacent upright support of frame T near the line of movement of said lever.

By the described construction the scraping side of the plow is in a simple manner made capable of being raised Without burdening the operation with the weight of the opposite side and the necessity and expense of an additional su pporting-sled is avoided, thus simplifyingthe plow and cheapeningitscostwithout impairing its effectiveness.
